The team is appealing a judge's July order canceling its trademark registration. The judge ruled the name Redskins may disparage Native Americans.

In a brief filed with the 4th U.S. Circuit Court of Appeals, the team says the federal trademark register is "infested with countless trademarks conveying racist and offensive messages" but insists that the name Redskins is not among them.

The Native Americans who challenged the trademark have until Jan. 14 to file their response.
